Well, for the second year in a row brooding ducklings, I've had one come down with wry neck. I am so frustrated! Last year, it showed up in one of my shipped ducklings; this year, it's in one of my home hatched. Last year, I started the ducklings on Southern States game bird starter, and when the one came down with wry neck, I switched them to Purina Start and Grow. This year, I started them on Purina Flock Raiser, and still I have a case of wry neck. Last year, I treated with niacin in the water, and Polyvisol and Vitamin E twice a day by mouth, and it did cure the problem. I've started the same treatment this time. There must be something I'm doing wrong, though, to have two cases of wry neck two years in a row. Any ideas?
